Auto Setup/Room Equalizer (Room EQ) Functions
• The AVR-2807’s auto setup and room equalizer functions use
the attached microphone to measure the acoustic properties in
the room and automatically make the optimum settings.
• The optimum listening environment at all listening positions in
the home theater is achieved so multiple listeners can enjoy
listening at the same time.
As shown in Example q, as you make the measurements,
move the microphone successively to the different positions in
which the members of the family sit within the listening area
surrounded by the speakers. For best results, make the
measurements at 6 locations.
Even if the home theater is only used by a small number of
people, as in Example w, more effective equalization can be
achieved by taking the measurements in the area around the
listening position.
• When the auto setup procedure is performed, one of the
following 3 correction curves can be selected for the room
equalizer function.
Audyssey:
The frequency response of all the speakers is adjusted to
achieve the optimum environment for the room’s acoustics.
Front:
This adjusts the characteristics of each speaker to the
characteristics of the front speakers.
Flat:
This the frequency response of all speakers flat. This mode is
optimum for playing multi-channel signal music.
2 About the main listening position (*M)
The “main listening position” refers to either the center of the
listening position or the position in which the user sits when
using the system alone. The distance to the speakers is
measured from this position.
•To make the sound field settings manually, see pages 56 ~ 59.

Mount the setup microphone on a camera tripod,
etc., and set with the receptor pointing towards

NOTE:
• Once the settings are completed, disconnect the setup
microphone.
Place the setup microphone’s sound receptor at the height
of the ears in the listening position.
Be sure that at the beginning, the measurement is started
with the microphone set up at the main listening position.
It is not possible to measure properly if there are any
obstacles between the speakers and microphone. Check
that there are no obstacles.
